The following are some best restaurants of western food style that I've dined in or other people have recommended.
Salty's on Alki Beach
This is a good seafood restaurant that is a bit up-scale, sitting at the beach, you would enjoy beautiful scenery looking at Seattle.
Space Needle Rotating Restaurant
The entire restaurant moves 360 degrees. After dinner, you can go to the observatory Deck to overlook Seattle.
Ivar's Seafood Restaurants and Chowder
Started in 1938, the full-service waterfront restaurant is nicely decorated. Food is delicious.
New Orleans Seattle Downtown Restaurant
Traditional and featuring America's musical heritage of jazz, blues. The shrimp JAMBALAYA is very good dish.
The Crab Pot Seattle
Seafood Restaurant in Seattle. Not not the best seafood in town but pretty good. It's a fun, different kind of experience. This restaurant is also available in Bellevue.
Elliott's Oyster House
Sitting on the waterfront overlooking Elliottt Bay, it is a seafood specialty restaurant.
